Can I add to my compressed air set-up?

That depends on your current consumption. Usually when we size a compressor we suggest a unit slightly larger than required (futureproof so that you do have some room for expansion of your business without having to replace the compressor so that then yes you can expand (within reason). The best thing to do is to add up the current consumption in cfm (cubic feet per minute) then find out the amount of cfm the new equipment will use and compare this to the output of the compressor. Always bear in mind bar pressure required as this affects the amount of cfm produced – the higher the bar required the lower the cfm.
